DOOR-LATCH.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed October 27, 1917. Serial No. 198,888.

To all whom it may concern:

Be it-known that I, ADDISON B. CARLL, a citizen of the United States, residing at New York, in the'county of New York and State of New York, have invented a new and useful Door-Latch, of which the follow ing is a specification.

This invention relates to a door latch, and more particularly to the class of upper or head fasteners for garage doors, or the like.

The primary object of the invention is the provision of a latch or fastener of this character, wherein on the closing of the door, the same can be fastened securely flush with the-door frame or jamb thereof, and will draw said door in place should the same be warped.

Another object of the invention is the provision of a latch or fastener of this character, wherein the same may be operated in the latching or unlatching of a door from either side thereof, the handle for operating said latch or fastener being located at a convenient height upon the door for the ready and easy manipulation thereof.

The invention has for a further object to improve devices of the indicated character in varying particulars, to the end that efficiency in operation may be promoted, as well as simplicity in construction and convenience of control and in installation. The invention will be particularly explained in the specific description following:-

Reference is to be had to the accompanying drawing, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all views.

In the accompanying drawing Figure 1 is a fragmentary elevation of a door looking toward its inner side, showin the latch or fastener constructed in accor ance with the invention applied.

Fig. 2 is an edge elevation partly in section.

Fig. 3 is a fragmentary detail vertical transverse sectional view.

Fig. 4 is a view similar to Fig. 3, showing a slight modification of the invention.

In constructing a practical embodiment of the invention in accordance with the illustrated example, the bearing plate 10 is provided, preferably comprising a base 11, having a hollow boss 12, which pro]ects outwardly from the outer face thereof, said base being secured to the inner side of the door A, (a portion thereof being shown), and located at the desired height thereon for the convenient and easy reach of the loopllke operating handle 13, the latter beng formed with a hub 14, which is loosely Journaled upon the boss 12, and is retained thereon in a manner presently described.

Passed transversely through the door A, is a bolt 12, which has its inner end extended through the hollow boss 12, and carries a threaded nut 16, which works against a washer 17 upon the bolt, the washer being designed to bear against the outer end of the boss 12 and, in this manner, the handle 13 is rotatably held upon said boss.

At a point near the upper edge of the door A at the inner side thereof, is secured a bearing, comprising a base 18, having a hollow boss 19 projecting outwardly therefrom, and upon this boss isjournaled the latch or fastener proper, which includes a hub 20 and a cam-engaging wing 21', which is integrally formed with said hub, said wing gradually flaring or widening from the hub outwardly, and having a partial spiral twist iven thereto as shown in Figs. 1 and 2-. Tile hub is also formed with an extension or arm 22, which is disposed at an angle to the wing 21, and has pivoted thereto a throw rod or link 23, which is also pivoted at 24 to the handle 13, so that on turning the latter, the fastener or latch proper can be thrown to latching or unlatching position. The cam wing is movable in a vertical plane toward and away from the edge of the door.

Passed transversely through the door A, and also through the hollow boss 19, is a bolt 25, which carries at its inner end a nut 26 and a washer 27, the latter bearing against the hollow boss 19 and the nut pressing against said washer, so that in this manner the hub 20 is rotatably held upon the boss.

Secured to the underside of the head of the door frame or casement, a portion B thereof being shown, is a keeper which comprises an angle plate 28, formed with a cam flange or portion 29, arranged contiguous to the path of movement of the cam wing 21, to be engaged thereby when the door A is closed, so that said wing 21 in coacting with the flange 29, will draw the door in place in the door frame or j amb thereof, without regard to the warped condition of the door, and in this manner the outer side of the door will be substantially flush with the outer side of the door frame or casement. This result is accomplished by reason of the peculiar disposition of the cam wing and the fact that the flange or engaging surface 29 is set at an angle to the door.

It will -be noted that the cam wing and flange are vbrought into engagement at a point short of the upper edge of the door.

Mounted on the base 10 1s a stop 30, which limits the swinging movement in one direction of the handle 13, the stop being located preferably at a point to limit the swinging of said handle in a direction to release the latch proper from its keeper, as is clearly shown by full lines in Fig. of the drawing, while by dotted lines is shown the other position of the latch or fastener proper for the latching of the door closed.

In Fig. 4 is shown a shght modification of the invention, wherein the looplike handles 31 are disposed on opposite sides of the door, the hubs 32 of which are engaged on the end portions of a squared pintle 33, whlch end portions carry the usual nuts and washers 34 and 35, respectively, for the fastening of the handles in place upon the pintle. The pintle 33 is mounted in a tubiformsleeve 36, which is mounted transversely 1n the door, and the hubs 32 of the handles abut against the ends of said sleeve 36, which ends slightly protrude beyond the opposite faces of the door, and have surrounding the same escutcheon plates 37, which are secured to the door in any suitable manner.

Pivoted to the innermost handle 31 is the throw rod or link 38, which is adapted to operate the latch proper on manipulating either of the handles 31, as will be clearly apparent.

The particular angular disposition of both the cam wing 21 of the latch proper and the flange 29 of the keeper, enable the secure latching of the door when closed and the drawing of the same into its seat within the door frame or casement, irrespective of the degree of warped condition thereof that might exist, so that the door when closed will have its outer side flush with the outer' face of the door frame or casement.

On manipulating the operating handle 13, or either of the handles 31, the latch proper can be conveniently and readily thrown to latching or unlatching position.

It will be noted that both the latch and its operating handle swing in a plane substantially parallel with the face of the door.

From the foregoing, it is thought that the construction and manner of operation of the fastener or latch will be clearly understood, and therefore a more extended explanation has been omitted.

It is contemplated within the scope of the invention to make changes, variations and modifications, such as come properly within the scope of the appended claims, without departing from the spirit of the invention, or sacrificing any of its advantages.

What is claimed is 1. A latch or fastener of the character described, comprising a handle adapted to be pivotally mounted upon a door, and to swing in a plane parallel with the face of the door, a latch proper adapted to be pivotally mounted upon the door near the edge thereof and also swinging in a plane parallel with the face of the door and having a hub vwith an outwardly flaring spirally twisted wing forming a cam, a keeper adapted to be secured to a door frame, to be engaged by said wing, the engaging surface of the keeper being set at an angle to the door and spaced from the face of the same, and connections between the latch proper and the handle, whereby in swinging the handle in one direction, the cam wing will engage the keeper and by swinging the handle in the reverse direction, the cam will be disengaged from the keeper.
